ok so i have a 1989 240sx sohc with the hud. but here is the problem. start my car up hud doesnt work. but if i turn my running lights on then flash my hazards on then off it comes on WTF!! that is the only way it comes on ive tried a bunch of ways. when it is on it is all working fine. but as soon as i turn my runners off it turns off too. it also turns off when i turn my wipers on. it never used to be like this. ive checked and replaced all the fuses so its not a fuse. so my question is were should i start tracing my wires? and if i buy an anolog will my speedo not work?

check your relay under the steering wheel collumn, make sure HUD is on doing your blinker problem thing, unplug relay, if they go out then its a relay issue.
